    Author: Yang GZ, Zhao S, Li YC.
    Journal: Yao Xue Xue Bao; 2002 Jun; 37(6):437-9. PubMed ID: 12579800.
    Abstract:
    AIM: To study the chemical constituents of Lycianthes biflora. METHODS: Column chromatography was used to separate the chemical constituents. IR, MS, 1HNMR, 13CNMR and 2D-NMR technique were used to determine the structures of the isolated constituents. RESULTS: Five compounds were isolated from this plant. Their structures were identified to be bifloride A (1), N-trans-cinnamoyltyramine (2), liquiritigenin (3), N-trans-p-coumaroyloctopamine (4), 1-O-beta-D-glucopyranosyl-2-N-2'-hydroxypalmitoyl-sphinga-4- trans-8-trans-dienine (5). CONCLUSION: Compounds 1 and 2 are new compounds, the others were isolated from this plant for the first time. Compound 2 showed inhibitory effects on P-388.
